SYMPTOM

CHECK

ACTION

REF

Output Voltage will not adjust.

Front panel CC LED is On.

Is the unit in constant current

mode?

Check Output Current

setting and load current.

5.2.1

5.2.2

Output Vol

tage will not adjust

Front panel CV Led is On.

Check if output voltage is

adjusted above OVP setting

or below UVL setting.

Set OVP or UVL so they will

not limit the output.

5.3

5.4

Output Current will not adjust.

Front panel CV LED is on.

Is the unit in c

onstant voltage

mode?

Check Output Current and

voltage setting

5.2

Large ripple present in output.

Is the power supply in

remote sense?

Is the voltage drop on the

load wire high?

Check load and sense

wires connection for noise

and impedance effects.

Minim

ize the drop on the

load wires.

3.9.4

3.9.8

No output. Display indicates

“OUP”

Overvoltage Protection

circuit is tripped.

Turn off the AC power

switch. Check load

connections. If Analog

Programming is used,

check if the OVP is set

lower than the output.

.3

No output. Front panel

ALARM LED is blinking.

Check rear panel J1

ENABLE connection.

5.8

Display indicates “ENA”

Setup switch SW1 setting.

4.4

Che

ck if air intake or

exhaust are blocked.

Check if the unit is

installed adjacent to heat

generating equipment.

Display indicates “Fb”

Check Foldback setting and

load current.

5.5

Poor Load regulation.

Front panel CV LED is on.

Are sensing w

ires connected

properly?

Connect the sense wires

according to User’s Manual

instructions.

3.9.8

The front panel controls are

non

-

functional.

Is the power supply in

Local

and wait until the display

turns off. Turn on

the AC

power and press front

panel REM/LOC button.

9.7 FUSE RATING

There are no user replaceable fuses in the power supply. Internal fuses are sized for fault protection

and if a fuse was opened, it would indicate that service is required. Fuse re

placement should be made

by qualified technical personnel. Refer to Table 9

-

2 for a listing of the fuses.
